BRAKE-GEAR MOUNTING.

Application filed May 9, 1927. Serial No. 189,795.

The mounting of the present invention is designed to meet the requirements of gearing of the type now commonly in use in connection with hand brakes for freight cars in which provision is made for the mounting and journaling of a pinion on the lower end of the brake shaft which meshes with a large gear mounted on the winding shaft for the brake chain. In brake gear mountings intended for this service, it has been customary to employ fittings and connections designed with reference to the particular or specific construction of the car for which the gearmounting was intended, and in most cases the mounting has been bolted, braced, angled, or otherwise secured to the longitudinal and cross sills of the car frame in some manner special to the framing of some particular type of car.

The present invention is so designed that it may be readily applied to cars of practically any standard type, since the mounting is designed to be connected with the under body frame only at the end sill and is elsewhere connected and supported from the car floor. In view of the fact that the mounting is thus secured to the car frame at only a single point, the present mounting is adapted for general use under conditions which would preclude the use of mountings specially designed to fit into the under body structure of some particular type of car.

A further object of the invention is to simplify the construction and method of securement, and at the same time make full and adequate provision for the strains and thrusts incidental to the employment of the device in actual service.

Further objects and details will appear 1U from the description of the invention in conjunction with the accompanying drawings wherein Figure 1 is a front end elevation of the mounting secured to the front of the car;

Fig. 2 is a side elevation of the mounting showing the car floor and end wall in section;

Fig. 3 is a top plan view of the mounting; and

Fi 4 and 5 are details showing variations in the form of the frame for the mounting.

The gear assembly for which the mounting is provided comprises a driving pinion 10 mounted upon the lower end of the main brake shaft 11, which pinion meshes with a large winding gear 12 mounted at the upper end of a winding drum or shaft 13. These features are common in the construction of this type of brake gearing and need not be further described in detail.

The gear and pinion are mounted within a gear housing open at its under side and comprlsing a top plate 14 provided with a de-, pending flange 15, the general configuration of the flange being circular with a protrusion 16 at its medial forward side for the purpose of housing the small driving pinion. The top plate 14 of the gear housing is of rectangular formation, so that it protrudes at its corners beyond the peripheral flanged wall of the housing, and the top plate is provided along each of its side edges with an upstanding flange 17, which flanges are riveted between and to the downwardly extending flanges 18 of a pair of parallel angle bars 19 which comprise the supporting frame and which may be separated and disconnected at their rear ends, although it is preferred to make the frame continuous and to give it either the U-shape configuration indicated in Fig. 1, or the rectangular configuration inso dicated in Fig. 5.

In the form shown in Fig. 4, the lateral flanges 20 of the angle bar frame are carried continuously around the curved rear end of the frame, while, as shown in Fig. 5, the flanges are notched out at the corners 21 leaving a separated rear flange 22. The lateral flanges of the supporting bar, however, are provided with bolt holes 23 for the reception of bolts 24 which are entered through the floor 25 of the car and secured by means of nuts 26, or in any other suitable manner.

The forward ends of the supporting frame members protrude forwardly beyond the front wall 27 of the car and under the front cross sill 28 to which the horizontal flanges of the frame members are secured by rivets 29, or in any other suitable manner. The connection is further reinforced by the provision of a front angle plate 30, the vertical flange of which is secured to the wall 27 and the vertical flange of .the end sill angle 28 by rivets 31, while the horizontal flange 32 is secured by rivets 33, thereby anchoring and reinforcing the forward protruding end of the supporting frame in a rigid and substanfiguration, and by upturning the edges of the l the load.

The lower end of the drum or winding shaft 13" is journaled through the web 3% of a hanger bracket-comprising side legs 35 and a medial front leg 36 reinforced by ribs 37, which legs at their upper ends merge into a substantially half circular rim 38 provided at its center front with an extension 39 configured to underlie the protruding wall flange 16 of the gear housing and having laterally disposed lugs 39 which register with similarly positioned lugs l0 on the gear housing to which it is connected by means of vertical bolts ll which also extend upwardly through the front corners of the top wall of the housing.

The main portion of the bracket rim follows the curvature of the main portion of the gear housing, and the rim is provided near each end with an outwardly projecting ear or lug 42 which registers with a similarly positioned lug 43 formed in each side of the gear housing, bolts 44 being provided to unite the parts together. By giving to the top wall of the gear housing a rectangular conwall to furnish, vertical flanges which lie betweenand abut against the verticalvfianges of the supporting frame a close andrigid unionis eifcted between the housing andjassociated parts which journal the gearing. The supporting frame furnishes the connectien with the bottom of the car body, and by V securing the frame both to the car H001 and to the front cross sill, a rigid unionis effected between the structure of the car and the mounting for the gears. Thus the gears are mounted immediately below thefront wall and cross sill of the car where rigidity of structure is greatest, but at the same time the rearward extensionof the sup 'iorting frame affords adequate reinfi'ircement which distributes the. strains and affords resistance against the upward thrust occasioned by the pull of the brake chain.

While it is preferred, where extreme ruggedness of structure is desired, to provide a supporting frame ofthe U-shaped character indicated. in Fig. 'which affords continuity both in the vertical and lateral flanges comprising the frame, nevertheless where condition, warrants, the frame shown in Fig. 5,

may be employed, or afranie composed of separate straight angle bars may be employed without departure from the principle of the invention.
